taxus atlas: taxus liberté™-sr stent for the treatment of de novo coronary artery lesions

Conditions: Coronary Artery Disease

Summary: taxus atlas is a global, multi-center, single-arm, non-inferiority trial comparing results from patients treated with the taxus liberté stent to an historical taxus express control. the control group is a case-matched, blended population of taxus express patients from the taxus iv and taxus v de novo clinical trials. the objective of the study is to evaluate clinical outcomes of taxus liberté-sr stent in de novo lesions and to assess the non-inferiority of taxus liberté versus taxus express. the taxus liberté-sr stent is hypothesized to have comparable safety and efficacy to the taxus express stent.
